Description

CCM663SR

The CCM663SR ceiling speaker features a woven Aramid Fibre coned twin voice-coil 150mm (6in) bass/midrange driver with an offset array of two 25mm (1in) soft dome tweeters. Thanks to its highly accurate and natural sound, Aramid Fibre features on our most advanced high-performance hi-fi speakers and it brings the same qualities to the CCM663SR.

Speakers with the Cinema icon are either dedicated products designed for multi-channel surround sound systems, or ones which we highly recommend for this purpose. It should be noted that the majority of speakers are suitable for use as surround and/or Atmos channels, so this icon does not apply to that application, and instead focuses on front speakers and subwoofers.

These speakers are single stereo models. They feature dual tweeters and separate left and right inputs to provide stereo sound from a single speaker. They are a popular choice for smaller spaces like bathrooms and en-suites. This type of speaker must be wired back to an amplifier using 4-core cable.

This icon indicates the size in inches of the speaker’s main drive unit(s). As a rule, larger drivers can produce lower frequencies for better bass response. They also typically have a higher maximum power handling.

Measured in ohms, impedance is the resistance or load that a speaker puts on an amplifier. When multiple speakers are connected to an amplifier channel in parallel (doubled up on the terminals) this actually has the effect of reducing the total resistance (1/Rt = 1/R1 + 1/R2 …). Most amplifiers are rated at 4-16 ohms, so care should be taken to stay within this range. If the total impedance in parallel is less than 4 ohms then the speakers should be wired in series.
